Abstract:
Syringocystadenoma papilliferum (SP) is a rare benign hamartomatous malformation of skin which arises from apocrine or eccrine sweat glands. Skin of the head and neck is the usual site for this but rarely involves the eyelids. It is also called as a childhood tumor since it usually appears at birth or during puberty. The diagnosis is confirmed on histopathological examination after surgical excision. We are first to report a case of SP involving the caruncle in an elderly female.

Exocrine Glands: Methods of Secretion
Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine...
